The kind of headers such as "this will make the conspiracy theorists look like twits" or "so what if the Americans really hate Iran" may have a basis in reality, but it also betrays, yet again, the kind of disdain with which the mainstream media views anything it was not fed on one sheet of A4 with the important bits highlighted in flourescent pen.
As for the substantive points, about national security, etc., yes it is embarrassing, but diplomacy, spying and candid appraisals of the opposition are not new. What is new is the mode of dissemination. Yet again, the worldwide web has escaped the control of those who think they have a right to run the world. They don't like it. They don't like it at all.
There is an odd corollary of this; The more "democractic" the country, the worse this type of leak is. If it had been about the Russians, instead of the US, they would not only have denied it, but they would have accused the opposition of black propaganda and sent out a hit squad to administer a Marie Curie Cocktail (Two parts Polonium, one part vitriol, and a dash of bitter almond). As it is, we get embarrassed about being found out to be not quite as polite as we like to think we are.
Wikileaks has caused alarm, not necessarily because of the revelations, but because "they" have lost control of the agenda. And in a world that should be free, that cannot be a bad thing.
This isn't Wikileaks the national disaster, this is Wikileaks the new red top. (Houdini)
